ABSTRACT:
An assembly for supporting a sign post or the like which releases the same upon impact by a vehicle includes a lower support member connected to a stationary footing and an upper support member fixedly connected to the post. The upper support member is releasably connected to the lower support member by means of breakaway coupling members which have weakened portions between the support members. Each coupling member is adapted to be severed upon application of a combination of excessive bending moments and axial forces thereto. The upper support member has load concentrating elements projecting therefrom which cooperate with the coupling members to equalize the bending moment produced thereto only upon application of wind load or the like to the signpost or the like at a point remote from the upper support member. The assembly compensates for or negates the effect of the bending moment produced from wind loads while impact of the post by a vehicle proximate to the upper support member is not compensated for by the assembly and readily releases and displaces the post to minimize damage to the automobile and injury to its occupants.
